METHOD FOR PRODUCING SOLID CATALYST COMPONENT FOR OLEFIN POLYMERIZATION, OLEFIN POLYMERIZATION CATALYST, METHOD FOR PRODUCING OLEFIN POLYMERIZATION CATALYST, AND METHOD FOR PRODUCING OLEFIN POLYMER

Document Type and Number:

WIPO Patent Application WO/2019/124021

Kind Code:

A1

Abstract:

A method for producing a solid catalyst component includes bringing a magnesium compound, a titanium halide compound, and one or more internal electron donor compounds into contact with each other to effect a reaction; washing the resulting product with a first inert organic wash solvent that does not have reactivity with the titanium halide compound, and has a solubility parameter (SP) of 8.0 to 9.0;washing the resulting intermediate product one or more times in the absence of the titanium halide compound with a second inert organic wash solvent that includes a hydrocarbon compound and does not have a reactivity with the titanium halide compound, but has a solubility parameter (SP) of more than 9.0; and washing the resulting product in the absence of the titanium halide compound with a third inert organic wash solvent that does not have reactivity with the titanium halide compound, and has a solubility parameter (SP) of less than 8.0.
